102 OBELISCELLA. 



those given by Paladilhe and by von Martens. The form de- 

 scribed by von Martens has been renamed by Jousseaurne, 

 without seeing specimens or indicating any differences. 

 While somewhat smaller than the types, there seems to be no 

 adequate reason for giving it a name. The description 

 follows : 



Var. martensi Jousseaume. Shell cylindric-turrite, lightly 

 striatulate, glossy, reddish- corneous; apex obtuse, subglobose. 

 Whorls 9, flattened, joined by a whitish, moderately impressed 

 suture, regularly increasing, the last shortly tapering at the 

 base. Aperture a little oblique, over one-fourth the total 

 length, subovate, acutely angular above, the peristome unex- 

 panded; a little thickened. Columellar margin rather ob- 

 lique, basal subangular, above dilated and appressed, pass- 

 ing into a distinct parietal callus. Length 11.5, diam. 3.33, 

 aperture 3 x 2 mm. (Marts.).

 western outliers of the Yemen mountain region (Schwein- 

 furth) . 



0. BENTUE (Melvill & Ponsonby). PI. 26, fig. 34. 



Shell cylindric, tapering, scarcely pellucid, straight, pale 

 ochraceous; whorls 10, smooth, but slightly ventricose. 

 Aperture ovate, peristome simple, a little thickened. Length 

 14, width 4 mm. A conspicuous shell, pale ochraceous in 

 color, non-transparent, cylindrical, attenuate, etc., named in 

 honor of the collector, Mrs. Bent (M. & P.).

The opacity of this shell may perhaps be due to the dead 

 condition of the specimens. In other respects it seems to 

 bear a suspiciously close resemblance to Obeliscella lucidis- 

 sima. I have not seen the species. Melvill and Ponsonby 

 institute no comparisons, and do not seem to have given much 

 attention to the literature of Arabian snails.
